Description Perennial herbs. Rhizomes obliquely ascending, slender, woody, stoloniferous. Culms 12–30 cm tall, obtusely trigonous, slender, slightly scabrous, glabrous, base with brown or pale brown sheaths, sometimes split into fibres. Leaves longer than culms or, sometimes, nearly equal in length; blades 1–2 mm wide, herbaceous, flat or margin slightly involuted, scabrous on upper margins and abaxial leaf surfaces. Lowermost bract shortly leaf-like, uppers setaceous, shorter than spikes, sheathed; sheaths 6–12 mm long, upper ones gradually shorter. Spikes 2 or 3; terminal spike staminate, clavate, 2–3.5(–4) cm long, 1.8–2 mm wide, long-pedunculate at base; lateral spikes pistillate, loosely flowered, cylindrical or shortly cylindrical, 6–15 mm long, 2–2.5 mm wide, base with peduncles enclosed in bract sheath. Staminate glumes oblong or oblong-elliptic, 4–4.5 mm long, pale yellow or pale brown, obtuse at apex, green or brown 3-veined dorsal costa. Pistillate glumes ovate or broad-ovate, 1.5–1.8 mm long, pale yellow-brown, acuminate at apex, green 3-veined dorsal costa excurrent into a mucro or short-awn. Utricles brown-green, obovoid-ellipsoid (excluding beak), obtusely trigonous, 2.8–3.2 mm long (including beak), longer than pistillate glumes, membranous, distinctly thinly veined, sparsely puberulent, base attenuate and stipitate, apex gradually contracted into a ca. 0.3 mm long beak, orifice 2-lobed with minute teeth. Nutlets tightly enveloped, ovoid, trigonous, pale brown or yellow-brown, ca. 2 mm long, slightly excavated below, base with a ca. 0.2 mm long stipe, apex abruptly discoid-annulate or inconspicuously discoid-annulate; style thickened at base; stigmas 3.

[details]Diagnosis This new species is similar to Carex sachalinensis F.Schmidt in having lowermost bract shortly leaf-like and utricles short-beaked, but differs by having leaf blades 1–2 mm wide (vs. 2.5–3.5 mm wide), utricles longer than pistillate glumes, with beak margin smooth (vs. barbate) and lateral spikes 1 or 2 (vs. 2 or 3), with peduncles enclosed in bract sheaths (vs. enclosed in bract sheaths).

Etymology The specific epithet ‘linanensis’ refers to the type locality of this new species which was collected from Mount Daming of Lin’an District in Hangzhou. [details]
